OK, this is an easy one. The simple answer is not buy a Bose system. Here's why...
Bose is good at one thing, marketing. There is also a nice little ryhme that goes like this, "No highs, no lows, must be Bose". Granted Bose does penetrate the market and makes you believe that you are getting a lot for your money, but if you are truly looking for something to grow with, then Bose it not the answer.
For about the same money you would spend on a Bose system, you can get a HTIB that you "might" be able to grow with. I say "might" because some HTIB systems are limiting, but with a little research you can find one that will help you get your feet wet in the HT arena.
I would recommend starting here and reading a few reviews http://www.hometheatermag.com/hometheaterinabox/ You can get a passable HTIB for not that much money. After a few years of discovering the limits of your first HTIB, then you can start working on a true HT.
Here's a couple of other items to think about when setting up a HT. Your video device is a very small part of the total solution. You have to have good sound and the right environment to get the most from yout HT. Your room's acoustics and light control make a larger impact than 95% of people ever think about.
